Malossi Fly Clutch and Bell for Piaggio and Aprilia 400 and 500

Malossi Fly Clutch and Bell for Piaggio 400 and 500cc Scooters. The Best Clutch for Your Scooter. 

Centrifugal Clutch System with Clutch Bell for Sport Use
System comprises the famous:
    Reinforced clutch for extreme street use (Fly Clutch)
    In addition, steel (DC04) clutch bell (Clutch Bell) dynamically balanced.
Malossi Fly Clutch
The Malossi Fly clutch is the result of the experience that Malossi engineers have accumulated on the race track and the busy streets of Italy. This new clutch has been designed and constructed to fit perfectly in a standard vehicle and guarantee impeccable performance on all occasions. Malossi Fly Clutch is supplied precalibrated according to instructions supplied by Malossi engineers after exhaustive testing on accelerometer benches to check the reliability of every part. Malossi's Fly Clutch is designed with particular attention to dimensioning and material selection.
The Malossi Fly Clutch is a high-technology replacement that offers maximum reliability and extremely long life. 
Fly Clutch is a reinforced centrifugal clutch designed to easily withstand extreme operation, for example, constant stop and go on steep roads, city traffic, long series of traffic lights, especially with a passenger, and during hot weather when it becomes difficult to control scooter temperature levels.
Fly Clutch profits greatly from Malossi's experience, results acquired from research and thousands of tests performed in the field of scooter racing.
Malossi Clutch Bell with Reinforced Cooling Ring:
The clutch bells with reinforced cooling ring consist of a finned annular reinforcement producing excellent heat dissipation caused primarily from stand still starts and quick accelerations from low speeds.
This technological innovation resulted from extensive testing within the Scooter racing circuit.
The clutch bell design is based on the following principals:
Greater heat transfer surface area (finned section) lowers the working temperature of the clutch bell which dramatically increases the systems durability.
The clutch system is enormously stressed in city street riding, starts uphill and tight turn exits with a passenger.
That is why Malossi has fine tuned the Clutch Bell to protect your clutch.
The finned reinforcement ring is also a safeguard against failure. It has been designed to resist the elevated centrifugal forces due to large rotational speeds generated by high performance engines. Keep in mind that centrifugal force increases by the square of the rotational speed.
Bell housing made of ductile steel and deep drawn;
Spline hub made of special steel, machined, welded and broached;
Frictional working surface machined to tight tolerances;
100% Dynamically balanced;
Nitride surface hardened.
